In the statistical procedure, the budget billing amounts are not posted as debits until they are paid by the customer.
In the partial bill procedure, the individual amounts are posted directly as debits.
In the budget billing plan, an average amount is determined either by simulation or manually. The customer pays this average amount for a period of 12 months. At the end of this period, a new simulation is run for the next period. In addition, actual consumption is calculated monthly, and the results are printed on the bill. In addition, the difference between the customer's actual consumption and the average amount is calculated, updated monthly, and printed on the bill. In the last month of the billing period, the actual amount and the accumulated difference are billed.
In average monthly billing/equalized billing, the customer is charged an average amount based on billings over the last 12 months (or less in the case of new customers). In addition, actual consumption is calculated monthly, and the results are printed on the bill. The amounts due for later months are calculated using the average of the previous (maximum 11) months plus the current bill and the accumulated difference. This difference is updated monthly and is also printed on the bill. In final billing, the amount due is derived from the actual consumption and the accumulated difference.
In the payment scheme, the bill amount from the latest billing is copied to the next budget billing plan. This means that the bill amount need not be cleared through a direct payment. The budget billing amount is made up of a portion of the bill and a portion of the extrapolation for the subsequent budget billing periods.
